Description

A driverless LED reflector lamp

technical field

The utility model relates to the technical field of LED lighting fixtures, in particular to a driverless LED reflector lamp.

Background technique

As the fourth generation of lighting fixtures that are green, energy-saving, power-saving, and long-lived, LED light sources have sprung up, received wide attention, and are developing rapidly in full swing. The current LED light source is a low-voltage, high-current semiconductor device that must provide a suitable DC current to emit light normally. The technology of DC driving LED light source to emit light has become more and more mature. Since the power supply used in our daily lighting is high-voltage AC (AC100-220V), it is necessary to use step-down technology to obtain lower voltage. The commonly used ones are transformers or switching power supplies. Step down, then convert the AC to DC, and then convert it to a DC constant current source to promote the LED light source to emit light. Therefore, there must be a certain space in the LED lamps of the prior art to install the driver module, resulting in the LED lamps with drivers usually having a complicated structure and relatively high manufacturing cost. Moreover, the lamp body of many existing LED lamps is Traditional metal materials such as aluminum have poor insulation performance and cannot withstand high voltage. There are also some LED lights that flicker during the light-emitting process. Long-term use of such LED lights in such an LED light environment is likely to damage the eyesight of users.
